目的通过对比SAS和LISREL软件在结构方程模型运算过程中的程序特点和结果差异,为结构方程模型应用者提供参考。方法运用SAS和LISREL,采用Monte Carlo数据模拟实验对预设模型进行分析。结果 SAS和LISREL对同一参数和统计量的输出结果相同;LISREL输出了更加丰富的拟合指数,并能提供较为直观形象的含有路径系数的路径图;SAS的编程语句直观明了,更易被具有计算机编程基础或者专业统计分析人员所掌握。结论应用者可按照自身专业背景和对两个软件使用的熟练程度灵活选择两种软件。
Aim To compare the difference of program features and results between SAS and LISREL software in the process of structural equation modeling, and to provide a reference for the application of structural equation model. Methods Using SAS and LISREL, the Monte Carlo data simulation experiment was used to analyze the preset model. Results The output of SAS and LISREL for the same parameters and statistics are the same. LISREL outputs a richer fitting index and provides a more intuitive path map with path coefficients. The SAS programming statements are intuitive and easy to be used by computers Programming basis or professional statistical analysts grasp. Conclusion Users have the flexibility to choose between two types of software based on their professional background and their proficiency in using the two softwares.
